I am working with a Redhat 7.4, this machine doesn't have internet connection, and I want to install Docker, therefore I downloaded a rpm package, this one:
docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpm
I used the command yum install
and apparently all the process went fine but my issue begins when I use sudo systemctl start docker
I get this:
Failed to start docker.service: Unit not found.
I tried the solution in this topic: Cannot start docker daemon in CentOS7 | Stack Overflow and my issue wasn't solved, I wrote this in the document docker.socket
[Unit]
Description=Docker Socket for the API
PartOf=docker.service
[Socket]
ListenStream=/var/run/docker.sock
SocketMode=0660
SocketUser=root
SocketGroup=docker
[Install]
WantedBy=sockets.target
when using the command sudo systemctl start docker.socket
it throws this:
Job for docker.socket failed. See "systemctl status docker.socket" and "journalctl -xe" for details.
Then I used this command sudo systemctl status docker.socket
and got this
docker.socket - Docker Socket for the API
Loaded: loaded (/usr/lib/systemd/system/docker.socket; disabled; vendor
preset: disabled)
Active: inactive (dead)
Listen: /var/run/docker.sock (Stream)
mar 02 10:19:28 machine.name systemd[1]: Socket service
docker.service not loaded, refusing.
mar 02 10:19:28 machine.name systemd[1]: Failed to listen on Docker
Socket for the API.
This is what I get when using journalctl -xe
No journal files were found.
-- No entries --
I am all stuck in this issue and I don't know what else to do/try; I am a bit new with Linux therefore I might be missing something.
EDIT 1
I've tried the command rpm -qa | grep docker
and this is what I got:
docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch
Best Answer
If you must install a
Centos
package onRHEL
then the package that you actually want is:docker-ce-17.12.1.ce-1.el7.centos.x86_64.rpm
You can download it elsewhere and then bring it over to your machine. The link to the package is 'https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-17.12.1.ce-1.el7.centos.x86_64.rpm`
You will also need the package:
container-selinux-2.36-1.gitff95335.el7.noarch.rpm
as it is a dependency. It can be obtained fromhttp://mirror.centos.org/centos/7/extras/x86_64/Packages/
Before you begin, either
yum remove docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpm
orrpm -e docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpm
as they may conflict withcontainer-selinux-2.36-1.gitff95335.el7.noarch.rpm
After the packages I mentioned are on your machine, you can install them one of two ways:
yum install container-selinux-2.36-1.gitff95335.el7.noarch.rpm docker-ce-17.12.1.ce-1.el7.centos.x86_64.rpm
rpm -ivh container-selinux-2.36-1.gitff95335.el7.noarch.rpm docker-ce-17.12.1.ce-1.el7.centos.x86_64.rpm
After installation,
systemctl list-unit-files | grep docker
which will showdocker.service
systemctl enable docker
systemctl start docker
systemctl status docker
You will see the docker service started and running.
